Title: Process for the fault monitoring of an electric valve
Inventor: HAEUSLER MICHAEL
IPC: H02M1/088
Filed: 1987-05-28
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE          With electric valves (7) having several series-connected thyristors (T1 ... Tn; T1'... Tn'), individual thyristors may become defective, so that they do not withstand the blocking voltage applied to them.  For the simplified checking of such defects, a process is specified which does not require any individual monitoring on the spot, i.e. for high potential.  For this purpose, in the blocked state of the valve (7), all thyristors of one current direct-ion, apart from at least one thyristor being tested, are triggered within a predeterminable triggering interval.  If a valve current (iR then flows, an indicating and registering device (A1 ... An) in-dicates in which thyristor stage the defect has occured.  This status check is preceded by a pre-liminary test in which it is checked whether all thyristor triggering channels are in order.  All thyristors are triggered in this test.  If no valve current (iR) occurs, a triggering channel fault signal (SuO) is generated.

Abstract: The   novel   fast-drying   pressure-sensitive adhesives comprise a polymer of a terminally unsaturated vinyl monomer such as isooctyl acrylate and an emulsifier monomer such as sodium styrene sulfonate plus a phosphate emulsifier, especially certain polyoxyethylene phosphates or  salts  thereof.    Pressure-sensitive  adhesive  tapes comprise a backing and the novel adhesive.  The novel tape is particularly useful  as  an automotive masking  tape, because it both adheres strongly and can be cleanly removed from automotive paints after typical baking cycles.   As compared to prior tapes the novel tapes have equal or better adhesive performance, with a faster drying adhesive layer.    The  tapes  can  therefore  be  produced  more economically.  Furthermore, there is no adhesive bubbling problem at commercially useful production rates as with the prior art when using a paper backing.

Granted: 1992-08-18
Abstract: Abstract of the Disclosure ________________________ A container for heating a substance, e.g. food, in a microwave oven has a bottom transparent to microwave energy.  The container is supported on a stand that contains one or more electrically conductive plates (or apertures in an electrically conductive sheet) that generate at least one mode of microwave energy of higher order than the fundamental modes.  The stand also serves to support the container above the higher order mode generating plates (or apertures) so that the undersurface of the substance is spaced from them by a uniform predetermined distance.  The arrangement has the known features of "bottom heating", i.e. taking advantage of the natural heat flow in the substance, while achieving more uniform heating of the substance by virtue of the higher order mode or modes.  As an alternative to or in addition to the generation of higher order modes, the stand may embody elements that modify the microwave pattern in a manner than enhances the coupling of microwave energy into the undersurface of the substance to be heated.
